Castle Jotunheim has gone through some radical changes. Originally just a single 2-foot square board, the castle essentially being a fortified cave and dual towers the Giants had built into the mountains. In February of 2025, it was been entirely rebuilt, now being a 2-foot by 4-foot wide fortification, including a gatehouse with working draw bridge and barbican and a length of curtain wall, implying a much larger fortification beyond.
